Hi All,

I need to place lists or vectors within dataframes as single  
elements.  However when I try this:

df=data.frame(y=1, x=I(list(c("a","b"), c("f","c"), c("a"))))
df

df[1,'x']=I(c("a","d"))

I get this error, even though I am using I():

Error in `[<-.data.frame`(`*tmp*`, 1, "x", value = c("a", "d")) :
replacement has 2 rows, data has 1

Note that this behavior does not match that described here <http:// 
finzi.psych.upenn.edu/R/Rhelp02a/archive/37297.html>  in this post  
from 2004.

Can someone please point me towards the right way to do this?

Thanks!!

Dan
